One must know that Emperor Level Experts were basically considered at the top in the Middle Three Heavens! The big clans also had higher level experts of the Monarch Level, but those individuals were mostly old monsters of god knows how many years of age. In fact, they wouldn't even show up once in decades! And, the ones who were somewhat extreme wouldn't even show themselves in 100 or 200 years…
Moreover, even their own clans had no way to determine whether these people were still alive or not…
Therefore, the invincibility of the image of the Emperor Level Experts had been deeply carved in the hearts of every single person in the Middle Three Heavens for a long time. So much so that there was even a saying in the Middle Three Heavens that 'A clan which didn't have Emperor Level Expert couldn't establish a strong foundation after its expansion'!
